The Performance Diesel Damper

Fluidampr invented the viscous performance diesel damper.
No other damper tames torsional vibrations like the original Fluidampr that's made in the U.S.A.

The buzz among performance truck owners is how well Fluidampr quiets and smooths out chatter in diesel engines. These smooth running engines gain HP and Torque. So if you're driving a tuned-up diesel pick-up...you've got to have a Fluidampr.

890101 Specifications:

  • Material = Steel
  • Black Zinc Finish
  • O.D = 8-3/8"
  • WT. lbs. = 23
  • Balance = External

It's important for the damper on your diesel engine to function properly. Stock elastomeric dampers have a short life span and do not control torsional vibrations at all RPM's. The rubber rings in stock dampers deteriorate. Fluidampr offers a superior performance that lasts.


 Stock Damper








A new Fluidampr on your diesel truck will not only protect your engine from destructive but will also increase TORQUE & HORSEPOWER. High performance diesel engines running chips and programmers are exceptionally vulnerable to torsional vibrations. Save your crank & more by installing a new Fluidampr today.

Nice Damper

I just installed this balancer two days ago. It does smooth out the engine. The engine shuts off smoother without shaking. It was easy to install without a press.

This thing was one mother to install, and after about 2 hours with no progress I just took it to the nearest shop and had them do it. Overall I think it is a good investment because it makes the engine run smoother and is even more quiet than before.
Nice Piece of Equipment

This thing is like installing something from hell, it is extremely difficult to install. But I think overall it was probably worth it. I say it only because the engine runs even quiter, pretty amazing, and you will get a few extra horses.
